NEW YORK, N. Y., A CORPORATION OF NEW YORK REPLAGEABLE -REGEPTAGLE cLosUnrz Application led May 25, 1928.- Serial No. 280,498.

The invention relates to new and useful improvements in metal receptacles and more particularly to a metal receptacle wherein the wall of the body is folded to form a reinforc- 5 ing band adjacent one end thereof and is also provided with score lines in the region of said band to 'form a tearing strip by which the receptacle maybe opened.

An -object of theinvention is to provide a 10 receptacle of thel above character wherein the blank forming the body of the receptacle is so shaped that the ends of the layers of the reinforcing band` may be firmly ljoined by a bonding material .without requiring the overlapping of the ends of the inner. layer of the band so that the innervwall of the band of the receptacle will' be of uniform diameter throughout to receive and frictionally hold the detached end .when the receptacle is A further object of the invention is to provide a receptacle of the -above type wherein the ends of the reinforcingv band are firmly united by abutting the ends of the inner layerl and abutting the ends of the intermediate layer and arranging said abutted ends in staggered or olfset relation to each other.

opened by the removal of the tearing strip. f

Figure 6 is a plan view of the blank showing the configuration of the ends of the blank.

Figure 7 is a plan view of the blank shown in Figure 6, folded in reparation for forming the body portion o the can.

Referring by numerals to the drawings i which the samel and similar elements are A portion of one edge of the blank is cut away to form a projection 5, and the correspondingportion of the opposite edge cut away to form an 'indentation 6 somewhat deeper than the projection 5, so that when the edges 2 and 3 are joined, the projection 5 will abut the edge of the blank in the indentation 6 and the edge 2 will overlap the edge 3, the distance of the base of the indentation 6. Avportion of the edge 3 of the blank is also cut away above the projection 5 at 7 and the corresponding edge 2 cut away half the vheight/and width of the cut-away portions 7 at 8, so that when the can is formed, the edge of thel cut-away ortion 8 will abut the edge of the lower hal of the cut-away portion 7 at a position dis laced from the abutting edges of the inner ayer.

The edge 2 above the cut-away portion 8 is cut away at 9, forming a rojection 11. The same edge of the blank a ove the cutaway portion 9 is extended outwardly to form ai. tongue 12 havingthe upper edges terminating in a cut-away portion 13 correspon with the cut-away portion 9, immediatelybelow the tongue .to facilitatethe removal of the tearing stri The outside Pace of the blank is scored at 14 and 15 on lines parallel with and terminating at the'top and bottom e of the tongue 12. In this manner the portlon of the blank above the score-15 ma enbe removed b' gaging the tongue wi a conventional key .up layer.

and outer layers and between in the usual manner, and the can body separated along the scores 14 and 15.

The blank is adapted to be folded outwardly along the line 16, so that the portion above the projection 5 and the indentation 6 will overlap the remainder ofthe can body. The blank is also desi ed to be folded inwardly along the line 1%? so that it will overlap the portion of thecan bodyy between the lines 16 and 17, thus forming a triple layer band consisting of an inner layer 18, a middle layer 19, and an outer layer 21. j.

The ends of the inner layer 18, consisting of the projection 5 on the edge 3 of they corresponding cut-away portion 6 in the edge 2, are adapted to abut and form a joint 22 at an angle to the side seam, as shown in Figures 2 and 4. The vertical edges of the inner vlayer 19. are adapted to abut and form a joint the side seam at 23, as shown ininline with Figure 2, and the edge 2 of the outer layer 21 is adapted to overlap the edge3 and form' a joint 24, as shown in Figure 2.

From the above it will be apparent that the body of the receptacle has been provided with a reinforcing band adjacent one end thereof by the folding of the metal blank which is to form the body. The blank is so shaped that when the edges of the blank are brought together in the side seam the ends of the inner layer of 'the band will abutted and this will form a body portion which in the region of the band is of uniform diameter. The ends are very. stron ly united by the bonding solder as the abutted ends of the inner layer and the intermediate layer are oiset or staggered. This roduceg af conf struction wherein one end o 4the inner layer overlaps the opposite end ofthe intermediate lThe solder as it'flows or sweats into the joint uniting the endsof the band will secure these overlapped parts together 'and this 'will form a very strong tie uniting the ends of the band.

Furthermore, the abutted edges of the inis termediate layer are inclined to the line of the side seam and this further'distributes the strain. The ends of the outer layer of the band are in part lapped and the projecting tongue of the tearing strip overlies the other end of the tearing strip. LThe side edges beneath the band may be either interfolded to form a lock seam or lapped to form a lap seam, as noted above, and the edges above the band are lapped. The abutted edges of the inner layer and the intermediate layer are disposed within the limits of the side seam so that the bonding solder applied to the outside of the side seam will sweat in between the intermediate layer and abutted edges of the along the lapped end portions of the innerv edges of the inner layer thus formin firm umon between the side edges of a very e body the abutted container is provided with a flan e 25 and this flange and the outer edge o the end closure 26 are rolled into a double seam 29.

' The end of the receptacle is provided with the usual depression directly)7 in rear of the double seam 29. The closure end is also provided with a depression 27 which is of slightly less diameter. This depression 27 forms a friction wall, the diameter of which is such that said friction wall will it snugly within the receptacle body at the outer end portion of the band.

When the tearing strip is removed the closing end 26 isureleased from the receptacle and can has a very smooth u r edge and the raw edge of metal forme Ee the lower score line 14 is well beneath sai smooth up er edge. The score line 15 at the upper s1 e of the tearing strip is close to the double seam and the raw edge of metal here is well protected by the double seam.

In the form shown in Fig. 1 the friction wall is in engagement;` with the receptacle bod when the double seam is formed. The dou le seam is directly overv the outer layer of the reinforcing band and, therefore, the double seam is ofset outwardly from the fri'ction wall which engages within the body of the receptacle. The outset portion is indicated at 28 in Fig.' 1 of the drawings.

In Fig. 5 of the drawings, the score line 15 placed very near the upper edge of the band and the central depressed portion 27 does not make contact with the body of the receptacle until after the receptacle is o cned by t e removal 'of the tearing strip.' form of structure there is both an inside slip produced by the inner friction wall of the depressed central portion 27 and an outside slip 31 provided by the wall of thereceptacle which is above the score lines and attached by the, double seam to the closure end. When the closure end is replaced'on the rece tacle body the remaining portions of the ban pass in between the vertical wall on the central n this.

It is obvious that minor changes in the details of construction and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claims.

We claim:

l. A receptacle comprising a body portion having a side seam extending from end to end thereof and ends secured to said body portion, said body portion having the wall thereof folded to form a triple layer reinforcing band adjacent one end thereof and score lines forming a tearing strip whereby the end may be separated from the body portion for the opening of the receptacle, the ends of the inner layer of the band being abutted and the ends of the intermediatelayer of the band being abutted and staggered relative to the abutted ends of the inner layer Within the limits' of the side seam whereby the bonding solder applied to the side seam firmly joins the ends of said band.

2. A receptacle comprising a body portion having a side seam extending from end to end thereof and ends secured to said body portion, said body portion having the wall there. of folded to form a triple layer reinforcing band adjacent one end thereof and score lines forming a tearing strip whereby the end may be separated from the body portion for the opening of the receptacle, the ends of the inner layer of the band being abutted and the ends of the intermediate layer of the band being abutted and staggered relative to the abutted ends ofthe inner layer within the limits of the side seam whereby the bonding solder applied to the side seam firmly joins the ends of said band, vthe end adjacent the reinforcing band having a central depressed portion, the outer diameter of which is sub-- i stantially the same as the inner diameter of the receptacle whereby said end when released by tlie removal of the tearing strip may be inserted in the receptacle body and afford a friction reclosure therefor.
